Extended Data Fig. 1: Share of annual average irrigation surface water consumption 1985–2015 met by different sources.
Share of annual average irrigation surface water consumption 1985–2015 met by (a) snowmelt runoff, (b) rainfall runoff, and (c) alternative sources (for example, water stored in reservoirs and inter-basin transfers). Shares from all three sources are zero for basins without irrigation surface water consumption.
